Yes, the problem is quite strange as the installer tries to create the table, so there should not be a problem with the table not existing. Please restart your MySQL server and try to install again. If installer fails, try to run the following directly in phpMyAdmin
Code:
DROP TABLE xcas_impressions_temp;
Code:
CREATE TABLE `xcas_impressions_temp` (
`itemId` int(11) unsigned NOT NULL,
`itemType` varchar(255) NOT NULL,
`dateline` int(11) unsigned NOT NULL
) ENGINE = InnoDB CHARACTER SET utf8 COLLATE utf8_general_ci;
Let us know the results.
Also please let us know if impression statistics work on your board as expected. You can see in Stats page if you have any impression statistics stored for banners and zones.
Thank you!
